>> global warming -- we hear about it all the time. but do any of us do anything about it? >> yes, i try. i like -- i walk to school, and then i also shut the sink off and i take tubs so i don't waste water. so, i fill it up, and then i don't fill it up again. >> well i try to, like, recycle, and i tell, 'cause every day in school we're talking about global warming in our science classes. so, i try to, like, tell other people to recycle and just make sure those polar bears still stay safe. >> well, i try to unplug stuff after using it and all that. >> i think that i as a person try really hard to become eco-friendly and to take care of our environment. >> yeah, i have trouble with that. i probably should do more about it, but i'm very busy a lot of times. but when i can, i definitely do try to contribute less to the global warming.
